* make sure selected tracked value is an option if possible Before this case did not work correctly: - Select was rendered with *no* options, but *with* a saved value - Options were fetched by ajax and options prop was updated - Reduce function if passed What happens without this commit is that the selected tracked value simply was the raw reduced value (previously saved). Which means that displaying a label for example does not work if the label comes from the unreduced option. This commit makes sure that the internal tracked value is checked against all options not only once the select is created but additionally when options change. * remove useless keys - first key was always undefined - second key was always the index which is not usefull at all since it changes based on the order * add test for setting value after option changed * correctly react to value property changes if tracking internally fixes sagalbot#855, sagalbot#842 * add getOptionKey prop * yarn upgrade doc * add getOptionKey api doc and fix links * yarn upgrade * do not use key on slot * fix label spec

value
Contains the currently selected value. Very similar to a
value attribute on an <input>. You can listen for changes
using 'change' event using v-on.
value: {
default: null
},
options
An array of strings or objects to be used as dropdown choices.
If you are using an array of objects, vue-select will look for
a label key (ex. [{label: 'Canada', value: 'CA'}]). A
custom label key can be set with the label prop.
options: {
type: Array,
default() {
return [];
}
},
disabled
Disable the entire component.
disabled: {
type: Boolean,
default: false
},
clearable
Can the user clear the selected property?
clearable: {
type: Boolean,
default: true
},
maxHeight
::: warning Deprecated in v2.x & Removed in v3.0
This prop was removed in v3.0. You can use the $vs-dropdown-max-height
SCSS variable to adjust this setting in v3.x.
:::
Sets the max-height property on the dropdown list.
maxHeight: {
type: String,
default: "400px"
},
searchable
Enable/disable filtering the options.
searchable: {
type: Boolean,
default: true
},
multiple
Equivalent to the multiple attribute on a <select> input.
multiple: {
type: Boolean,
default: false
},
placeholder
Equivalent to the placeholder attribute on an <input>.
placeholder: {
type: String,
default: ""
},
transition
Sets a Vue transition property on the .dropdown-menu. vue-select
does not include CSS for transitions, you'll need to add them yourself.
transition: {
type: String,
default: "fade"
},
clearSearchOnSelect
Enables/disables clearing the search text when an option is selected.
clearSearchOnSelect: {
type: Boolean,
default: true
},
closeOnSelect
Close a dropdown when an option is chosen. Set to false to keep the dropdown open (useful when combined with multi-select, for example)
closeOnSelect: {
type: Boolean,
default: true
},
label
Tells vue-select what key to use when generating option
labels when each option is an object.
label: {
type: String,
default: "label"
},
reduce
When working with objects, the reduce prop allows you to transform a given object to only the information you want passed to a v-model binding or @input event.
reduce: {
type: Function,
default: option => option,
},
getOptionLabel
Callback to generate the label text. If {option}
is an object, returns option[this.label] by default.
Label text is used for filtering comparison and
displaying. If you only need to adjust the
display, you should use the option and
selected-option slots.
getOptionLabel: {
type: Function,
default(option) {
if (typeof option === 'object') {
if (!option.hasOwnProperty(this.label)) {
return console.warn(
`[vue-select warn]: Label key "option.${this.label}" does not` +
` exist in options object ${JSON.stringify(option)}.\n` +
'https://vue-select.org/api/props.html#getoptionlabel'
)
}
return option[this.label]
}
return option;
}
},
getOptionKey
Callback to get an option key. If option
is an object and has an id, returns option.id
by default, otherwise tries to serialize option
to JSON.
The key must be unique for an option.
getOptionKey: {
type: Function,
default(option) {
if (typeof option === 'object' && option.id) {
return option.id
} else {
try {
return JSON.stringify(option)
} catch(e) {
return console.warn(
`[vue-select warn]: Could not stringify option ` +
`to generate unique key. Please provide 'getOptionKey' prop ` +
`to return a unique key for each option.\n` +
'https://vue-select.org/api/props.html#getoptionkey'
)
return null
}
}
}
},
onTab
Select the current value if selectOnTab is enabled
onTab: {
type: Function,
default: function() {
if (this.selectOnTab) {
this.typeAheadSelect();
}
}
},
taggable
Enable/disable creating options from searchInput.
taggable: {
type: Boolean,
default: false
},
tabindex
Set the tabindex for the input field.
tabindex: {
type: Number,
default: null
},
pushTags
When true, newly created tags will be added to the options list.
pushTags: {
type: Boolean,
default: false
},
filterable
When true, existing options will be filtered by the search text. Should not be used in conjunction with taggable.
filterable: {
type: Boolean,
default: true
},
filterBy
Callback to determine if the provided option should match the current search text. Used to determine if the option should be displayed.
filterBy: {
type: Function,
default(option, label, search) {
return (label | "").toLowerCase().indexOf(search.toLowerCase()) > -1;
}
},
filter
Callback to filter results when search text is provided. Default implementation loops each option, and returns the result of this.filterBy.
filter: {
type: Function,
default(options, search) {
return options.filter(option => {
let label = this.getOptionLabel(option);
if (typeof label === "number") {
label = label.toString();
}
return this.filterBy(option, label, search);
});
}
},
createOption
User defined function for adding Options
createOption: {
type: Function,
default(newOption) {
if (typeof this.optionList[0] === 'object') {
newOption = {[this.label]: newOption}
}
this.$emit('option:created', newOption)
return newOption
}
},
resetOnOptionsChange
